Gail initially claimed that her prints were most likely from when Jade came into her exchange office, while also expressing no knowledge of Jade's counterfeiting business. But later on, a photograph showed Gail and Jade together, proving that the women were friends when Jade was running her business in Spain. When confronted, Gail revealed that she was in fact friends with Jade at the time, but cut ties with her when she found out she was a counterfeiter.
But ultimately, the evidence revealed Gail as Jade's killer. As revealed by Gail during her confession, she had actually been persuaded by Jade to join her in her counterfeiting operation, replacing the money reserves at her exchange office with Jade's counterfeit bills. But eventually, Jade became impatient and began spending the counterfeit money, causing Gail to fear that the bills would be traced back to them and they would be caught. Desperate to cover her tracks, the evil Gail killed Jade by shooting her in the neck with a handgun, later disposing of the weapon in Wolf Park.
Gail also disposed of the chain for her pocket watch (which she had gotten Jade's blood on) in an ashtray at the park, with this being among the pieces of evidence leading ot Gail's villainous reveal. After failing to feign innocence when confronted with the evidence, Gail confessed to being Jade's accomplice and her killer, justifying her corrupt actions by pointing out how many people on Wolf Street got rich through shady dealings and that she had to stop Jade from getting them caught. Jade was ultimately sentenced by Judge Justin Lawson to twenty years in prison, to which the villainess bemoaned how her plan to be wealthy had failed.
- "No, I... lied when I said I'd stopped seeing her. Jade seemed so charming, her criminal life so invigorating. I got caught up in it all! When she arrived in Concordia, Jade saw where I was working, exchanging money for rich tourists. She said it was unfair I got to touch the money, but never to have it myself. She said there was a way we could team up so I could get a bigger piece of the pie!" (Gail revealing how she'd come to join Jade's counterfeiting operation)
- "People are making money hand over fist on Wolf Street through shady deals. Why can they get rich, but not me? So we devised the perfect plan. I swapped the counterfeit money with the cash reserves at the exchange, distributing the false currency to my customers. No one could trace it! But Jade got impatient and started spending the phony bills! I warned her to stop, but she wouldn't listen! I couldn't allow the money to be directly linked to us, I couldn't get caught. Jade had to be stopped... one way or another!" (Gail justifying her greedy actions and confessing to killing Jade Carnegie)
- "Can you blame me for wanting to get ahead? I'm not a rich foreign traveler or a greedy businessman... this was my only chance as a humble exchange clerk to make a future!" (Jade continuing to defend her actions in court)
